HOW TO USE AIRCRACK NG TO CRACK WEP MAC

In this command, you will have to specify the local MAC address (so make sure to use the correct MAC address. xor file to generate and ARP packet that can be injected and will help to get IVs. You should get “Got RELAYED packet!!” in order to be successfull. Now you can build a packet with packetforge-ng out of that 1500 bytes keystream Saving keystream in fragment-0219-185011.xor

Find wireless network (BSSID and ESSID) ( airodump-ng wireless_interface_in_monitor_mode).

Put wireless interface in monitor mode ( airmon-ng start wireless_interface).

So assuming that there is no MAC filtering, or you have managed to get a valid MAC address of a client (earlier, or by bruteforcing mac addresses 🙂 ), then this is what you can do if there are no active clients connected to the network at the time of the audit : I guess it makes the wireless network a bit safer, but a whole lot more useless as well. Ok, first of all, if MAC filtering is enabled and there are no active clients, it’s going to be difficult to get a valid MAC address that is allowed to associate with the AP. Scenario 2 : WEP encryption, OPEN Authentication, MAC filtering enabled (?), no active clients
